T at whom it may concern.-

Be it known that I, EDWARD NIDDs, a citizen of the United States, and aresident of the city of New York, borough of Brooklyn, in the county ofKings and State of New York, have invented a new and Improved LathingSystem, of which the following is a full, clear, and exact description.

My invention relates to lathing systems, and more particularly to thoseemploying metal. Its principal objects are to provide a convenient lathand to furnish a simple and strong construction.

Reference is to be had to the accompanying drawings, which form a partof this specification, in which like reference characters indicate likeparts in the several views.

Figure 1 is a broken top plan view of a lath made in accordance with myinvention. Fig. 2 is a side elevation thereof. Fig. 3 illus trates theinvention in connection with a ceiling or so-called flat arch. Fig. 4 isa broken front elevation of a vertical construction, as a wall orpartition. Fig. 5 is a horizontal sectional detail therethrough, takenon the line 5 5 of Fig. 4; and Figs. 6 and 7 are similar view of otherarrangements.

In Figs. 1 and 2 is shown one form of my improved lath, which ispreferably stamped from sheet metal 10 and is of a length and width mostconvenient for the uses to which it is to be put. The former dimensionis considerably greater, the laths thus being in comparatively longstrips. Each lath is divided into a lurality of sections 11, in whichare formed icy-openings 12 to receive and lock in place the plasterwhich is applied to the system in which the laths are employed.

These openings are preferably cross-shaped, they having intersectingarms 18 13, which are shown as situated at right angles to one another.The key-openings are arranged in series or rows both longitudinally andtransversely of the lath, and considering the transverse series the armsof each project between the corresponding arms of adjacent series, theopenings being in staggered relation to one another. This disposition ofkey-openings gives the maximum area with the minimum reduction ofstrength of lath and furnishes a particularly effective interlocking ofthe plaster. Extending across each of the sections 11 are longitudlnalcorrugations 14, which serve to strengthen the lath against distortion.These corrugations are shown as four in number, there being one at eachedge, and in these outside corrugations are formed slits 14", whichfurnish between them su porting-tongues 14 etween the sections 11 are saces 15, across which extend transverse in ex-marks 16, here shown asconsisting of small corrugations.) These furnish a guide by which thelath may be bent by the user to adapt it to various applications. Sevenof these index-marks are illustrated in each group, and from oppositesides of those at each side of the center extend locking-tongues 17,which may be bent from the plane of the surrounding metal to engagesupporting elements.

In the ceiling system (illustrated inFig. 3 of the drawings) beams 18are provided having flanges 19, which support intermediate flat bars 20.The laths are bent upon the index-marks to furnish transversedepressions which surround these bars. In the present instance thisbending is upon the center mark, the relation between the elementsbeing'such that this causes the sections 11 to lie below the plane ofthe bottom flanges of the beams, and the laths being bent until theadjacent edges meet beneath the bars they furnish an uninterruptedsurface to receive the plaster. It should be noted that the bars notonly support the laths, but that the laths in turn malntain said barsagainst lateral displacement. The system thus eliminates all auxiliarysecuring means either for the laths or bars. Though I have shown only aflat ceiling construction, it will be obvious that the invention isequally applicable to segmental arches. In fact, the arrangements inwhich it may be used are limited only to the capabilities of bending thebars and conforming the lathing.

To furnish vertical surfaces to receive the plaster, the laths may besimilarly bent, this being done upon lines which give the desiredair-space. Then the laths may be either fixed in place by nails driventhrough the bottom of the depressions or they may surround furringstrips or bars 21. To these they may be locked or clenched byalternately bendin the tongues 17 over the outer edges of the bars andinto the spaces furnished by forcing back the opposite tongues,-

as is shown in Fig. 5.- Here the outer series of said tongues is used,since the bars are of considerable width, or, as is shown in Fig. 6, theinner tongues may be bent over narrower bars 22 and similarly insertedthrough the opposite spaces. In Fig. 7 still another arrangement isillustrated, the outer tongues being alternately turned across a narrowbar 23. It will be clear that if a still greater airspace is desiredthan would be furnished by the depressions formed from single spacesthese depressions may be made to include the intermediate sections 11,the bending being done upon the index-marks at each side thereof. Inaddition to the support furnished by the nailing of the laths or byengagement of their locking-tongues they may be further maintained inthe proper relation to one another by pressing outwardly in oppositedirections the tongues 14* at the lower edge of each lath, so that theywill straddle the upper edge of those below them, thus positivelypreventing displacement by one another.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A lathing system, comprising bars, and laths havingportions surrounding and extending beyond the bars at one edge, andhaving interlocking engagement with similar portions of the laths.

2. A lathing system comprising bars, and laths having portionscooperating with the bars, said laths .being provided withlookingtongues.

3. A lathing system comprising bars, and laths having portionscooperating with the bars, said laths being provided with tonguesextending over the bars.

4. A lathing system, comprising a series of laths each provided withcross-shaped keyopenings, the arms of each opening of one series havingportions extending between those of an adjacent series, transversecorrugations extending between the key-o enings, longitudinalcorrugations extending etween the series of key-openings, transverseindexmarks extending between the sets of openings, and a series oftongues extending transversely across the laths between the indexmarks,said laths having portions adapted to surround and extend beyond theedges of a supporting-bar and interlocking with each other.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. I

EDWARD NIDDS.
